This reference combines a manual describing a range of  tractor-drawn cultivation tools (including illustrations, charts showing crop and weed height ranges for which each is suited, and written description and guidelines) with a series of farm stories illustrating successful mechanical weed management systems.  The book is divided into three sections addressing agronomic crops, vegetables and other horticultural crops, and dryland farming on limited rainfall, which have special soil conservation and soil quality challenges associated with weed management.  Although a number of newer tools have been developed for specialty crops since this book was published, it is still a valuable resource for organic farmers and others who avoid or minimize the use of herbicides for weed control.
